TRANSDUCER Some X-55A's are sold with a HS-WSBK transommount transducer. It can be installed on anyoutboard or stern-drive (inboarcf\outboard) powered boat. It can also be permanently installed inside the boat to "shootthrough1'the hull on some fiberglass boats.
The "kick-up" mounting bracket helps preventdamageif the transducer strikes an objectwhile the boat is moving. If the transducer does "kickup", the bracket can easily be pushed back in place withouttools.
ELEOThONICS LOWOANCE 12000EStSKELQY DONE1 ILILSA,OK 74120
If your unit came with a transducer, read this section carefully before
attempting the installation. Determine whichof the mounting positions is right for your boat. Use extreme care if mounting thetransducer inside the hull, since once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer location is the most critical partof a sonar installation. If it isn't done properly, the sonar can't
performat it's designed potential.
Location - General 1. The transducer must be placed in a location that hasa smooth flow of water at all times. If thetransducer is to be mounted inside the hull, then the chosen location must be in the water at all times. If the transduceris not placed in a smooth flow of water, interference will show on the sonar's display in the form of random lines or dots wheneverthe boat is moving.
KEEP THIS LABELl
Lowrance will pay UPS surface shipping charges both to and from the factoryforthis unitin the event it needs repair. Yourunitis insured against loss or shippingdamage when you usethe enclosed UPS label.
2. Slip thetransducer's mounting pad between the bracket's mounting "ears". Sandwich two internal lockwashersbetween thetransducer and one side of the mounting bracket as shown below. Place one washeron the other side of thetransducer.

3. Slide the metal sleeve over the bolt. Slip the bolt and sleeve through thebracket,washers, and transducer assembly. Place an internal tooth lock washer over the end of the bolt and thread the nut onto it. Do not tighten the nut at this time. The transducer is now ready for installation. INSTALLATION- Transom Mount 1. The transducer mustbe placed in a location that hasa smooth flow of water at all times. Air bubbles createdby themovement of the boat hull against the water interfere with thesonar signal. This causes "noise" or random marks to appear on the sonar's display. You may need to carefullyviewthewater'spath at the transomwhilethe boat is moving to determine the best location for the transducer.
When no noise appears onthe sonar unitafterall ofthe above tests,then the noise source is probably cavitation. Many novices or persons with limited experience make hastysonar installations whichfunction perfectly in shallow water, orwhentheboatis at rest. In nearlyall cases, the cause ofthe malfunction will be the location and/orangleofthe transducer. The faceof the transducer must be placed ina location that hasa smooth flow ofwaterat all boat speeds. Read your transducer owner's manual forthe best mounting position.
SHOOT-THRU-HULL INSTALLATION The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must passthrough solid fiberglass. A successful transducer installation oan be made on hulls with flotation materials (such as plywood, balsa wood, or foam) between layers of fiberglassif the material is removed from the chosen area. For example, some manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layerof fiberglass. Removing the inner layer of fiberglassand the balsawoodcore exposes the outer layerof fiberglass. The transducer can then be epoxied directlyto the outer layerof fiberglass. After the epoxy cures, the hull is watertight and structurally sound. Remember, the sonar signal mustpassthrough solid fiberglass. Any air bubbles in the fiberglassor the epoxywill reduceor eliminatethe sonar signals.
To choose the proper location for thru-hull mounting, anchortheboat in 60 feet of water. Add a little water to the sump of the boat. Plug the transducerinto thesonar unit, turn it on, then hold thetransducerover

the side of the boat. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (you will need to turn the automatic function off on L.C.G. units.) Don't touch the controls once they've been set. Next, take the transducer out of the waterand place it in the water in the sumpof the boat. Observe thesonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity. Move thetransduceraround to find the best location. If the sensitivity control has to be increased greatlyto compensate, then the transducer should be mounted on theoutsideof the hull. If not, then mark the location that shot through the hull the best and follow the instructions on the next pages for a shoot-thru-hull mounting.

2. Electrical noise fromthe boat'smotorcaninterfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. Thiscancausetheunitto eliminate weakersignals such as fish or even structure fromthe display. Tryusingresistorspark plugs or routing the sonar unit's power and transducercables away from other electrical wiring on the boat.
No fish arches when the Fish ID feature is off:
1. Make certain transducer is pointing straight down. This is the most commonproblem ifa partial arch is displayed. See the Fish Arch section in your owner's manual for more information. 2. The sensitivity maynot be high enough. In orderfortheunitto display afish arch, it hasto beableto receive thefish'sechofromthetimeitenters theconeuntil itleaves. Ifthe sensitivity isnot highenough, the unit displays the fish only when it is in the centerof the cone. 3. Use the Zoom feature. It is much easierto displayfish arches when zoomedin on a small range of waterthan a large one. For example, you will have much better Iuckseeingfish archeswith SOto60 foot rangethan a a0to 60foot range. Thisenlarges thetargets, allowing thedisplay to show muchmoredetail. 4. The boat mustbe moving at a slowtrolling speed to seefish arches. If the boat is motionless, fish stay in the cone, showing on the display as
straight horizontal lines.
Shoot-thru-hull Installation 1. Make certain the area is clean. dry. and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The surface of the hull mustbe flat sotheentire transducerface is in contactwith the hull priorto bonding.
NOISE A major causeof sonar problems is electrical noise. Thisusually appears onthesonar'sdisplay as randompatterns ofdotsor lines. In severecases, it can completelycover the screen with black dots, or cause the unit operate erratically, or notat all.
2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, as it will cause bubbles to form in the epoxy. (NOTE! Use only the epoxiesspecified on page 1 ofthis manual! Failure to use one of these epoxies may result in poor sonar performance!) Apply a small amounton the face of the transducer as shown above, then spread a small amount onto the sanded areaon thehull. Place the
Toeliminateor minimize theeffects ofelectrical noise,firsttrytodetermine the cause.With the boat at rest in the water, thefirst thing you should do isturn all electrical equipment on the boat off. Makecertain the engine is off, also. Turn your X-55A on, then turn off ASP (Advanced Signal Processing). There should be a steady bottom signal on the display. Now turn on each pieceof electrical equipment on theboat and viewthe effect on thesonar's display. Forexample, turnon thebilgepump and viewthe sonardisplayfor noise. If no noiseis present, turnthepump off, then turn ontheVHF radio andtransmit. Keep doingthisuntil all electricalequipment hasbeen turned on, theireffectonthesonardisplaynoted, then turned off.

1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work atall boat speeds. Air bubbles in thewaterdisrupt the sonar signals, interfering with its abilityto find the bottomor othertargets.Thetechnical termfor this is Cavitation.

The most efficient way to becomeacquainted with a bodyof water is to survey it with your X-55A. Start with a map of the lake, if possible, and indicate the promising spotsin relation to landmarks on shore. As you go aboutyour survey, yourX-55Awill tell youthedepth and type of bottom. It will also reveal suspended fish.
Keep afewmarkerbuoys in the boat, ready totoss overboard. When the X-55Aindicates a school offish, throwthe buoyout. Withtheschoolthus marked, youcanmake yourturnand come backto fish inexactlytheright spot. Thisis essentialwhen you'refarfromshore on abig lake.Unlessyou marktheschool of fish whenyou're over it, you may not be ableto find it again.
TheMetric label at the topof thescreen works thesameway. Pressthe key adjacentto the Metric labelto changethedepth from feetto meters. This also changes thetemperature displayto degrees Celsius, speedto knots, and log to kilometers on theX-55A. TheDisplay menu at the bottomofthescreen lets youadjustthedisplay's
However, situations occur where it becomes necessary to increase or decreasethe sensitivity. Thistypicallyhappenswhen youwishtoseemore so an increase in sensitivity is indicated. Theprocedure to adjustit detail, is the samewhetherthe unit is in theautomatic or manual mode. To adjustthesensitivity, press the SENS key. Thesensitivity adjust menu appearsat thebottomofthescreen. Thesensitivitymenu hasleftand rightarrows, plus ahorizontal bar graph. The graph gives a visual indication of the sensitivity level. The number abovethe INCarrow also shows thepercentage of sensitivity in use. To increase the sensitivity level, pressthe right arrow key. As you press the key, the menu's bar graph will grow wider and the percentage will increase in value.You can also see the difference on the chart record as it scrolls.Whenthe sensitivity is at thedesired level, release the key. the To decrease sensitivity level, press the key adjacent to the leftarrow. Thebar graph and percentagewilldecrease. When thesensitivity is atthe desired level, release the key. When you reach either the maximum or minimum limit, a tone sounds.
of Thetemperature waterinthe lake isseldom constantfrom topto bottom. (Seethepicture on the nextpage.) Layers of different temperaturesform, andthe junction of awarmand cool layerofwateris called a thermocline. The depth and thickness of thethermocline can varywith the season or time of day. In deep lakes there maybe two or more at different depths. Thermoclines are important to fishermen because they are areas where fish are active. Many times baitfish will be above the thermocline while largergame fish will suspend in or justbelow it.
TheX-55Acandetectthisinvisible layer inthewater, butthesensitivitywill probablyhaveto be turned up to see it. Whenthe Fish l.D. mode is off, the depth of thewaterwill affect the size and shape of the fish arch due to the cone angle diameter. For example, iftheconepasses overafish in shallow water, the signal displayed on the X-55A maynot arch at all. Thisis duetothenarrowconediameter and the resolution limitations of the display.

ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the X-55A that constantly evaluates the effects of boat speed, water conditions, and interference. This automatic featuregives youthe bestdisplay possible undermostconditions. TheASPfeatureisaneffective tool in combating noise. In sonar terms, noiseis any undesiredsignal. It iscaused byelectrical and mechanical sources such as bilge pumps, engine ignition.systems andwiring, air bubbles passing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display.
The ASPfeature has two levels - Normal and High. Ifyou havehighnoise levels, try usingthe "High" ASPsetting. However, ifyouare having trouble with noise, we suggest thatyoutakestepsto findthe interference source and fix it, rather than continually using the unitwith the highASPsetting. However, therearetimeswhenyoumaywantto turnthe ASPfeatureoff. This allowsyouto viewall incoming echoes before they are processed by theASP feature.

INTRODUCTION The LowranceX-3 Liquid CrystalGraph (LCG) is a compact unit that packs more power and featuresthan anyothersonar using a liquid crystal display (LCD.). The LCD. sets the X-3 apart from othersonar units. Insteadof a stylus writing on chart paper or a flashing neon light, the X-3 displays the depth information on a screen using small squares which turn black whenan echo is received. As each echo is detected,the signals move across the screen, leaving behind a record of the areathat was just passed.
No othersonar has as many automatic features as the X-3. Onceturned on, it will find and display the bottom signal, fish, and other targets.As the depth of the bottom changes,the X-3 will automaticallychange the range, sensitivity, and other controls so thatthe bottom will always be displayed on the screen.If desired, the only key on the keyboardthat needs to be touched is the off/on key. However,the X-3 hasbuilt in override capability that allowsthe features to be used in any combinationto bestsuit local conditions.

The power cable hastwo wires, red for the positivelead and black is ground or negative.An in-line fuse holdercontaininga 3 amp fuse is supplied with the X-3. Thisshould be attached to the red wire on the power cable with the crimp connector.Theother end of the fuseholder should be attached to the battery or accessory buss.If the cable is not long enough, splice ordinary #18 lamp cord to reach.Just be certain that the fuse holderis as close to the power source (batteryor accessory buss) as possible. This will protect the power cable and unitin the event of a short TheX-3 is protected from accidental polarity reversalsand will not be harmed if the wires are reversed. (However, the unit will not work until the proper polarity is applied.)
Electrical noise picked up by the power cable can be minimizedby routing it away from otherpossible sources ofelectrical interference.One of the largest noise generators is the engine'swiring harnessthat runs from the engine to the boat's instrumentpanel. This harness usually contains a wire for the tachometer which radiates RF (radio frequency)energy. For the bestresults,keep the power and transducer cables away from the engine wiring. Bilge pumps are also noisy, so try to keep the X-3's cables away from them,too. VHF radio antenna's coax cable radiate RF energy at higherpower levels than even the engines wiring hamess.It isvery importantto keep the X-3'spowerand transducer cables as far away as possiblefrom the VHF radio's antennacable.

When first turned on, the X-3 automaticallyadjusts the sensitivity, range, and chart speed according to water and bottom conditions. In fact, it can be leftin this mode and itwill track the bottom and display it atall times, automaticallychanging the range as the bottom depth varies. The sensitivity will also change as required, to keep the bottom signal displayed.If present,fish or other targets may be seen. At first, operate the X-3 in the automatic mode only.Just turn it on and watch it work. Then, read the following chapter on the X-3'sbasic operation and learn how to adjust it for your specific needs. Later, read the Advanced Operation section to make the most out of the X-3's remarkablecapabilities.

Should the display "freeze' check to see if the top line ofthe display or the digital bottom depth is flashing. If it is, then the unit is working, but the digital has lost the bottom signal, and it is trying to find it The chart stops scrolling when the digital loses the bottom. It will start moving again when the digital regains the bottom. If neither the top line of the display nor the digital bottom depth is flashing and the chart won'tscroll,then turn the unit off and backon again. Theunitshould begin working normally. If it cannot find the bottom signal, and youare in shallow water,(less than eight feet)following the directions on page 24 concerningshallow water operation may help.
Ifthe unit doesn't turnon when the ON/OFF key is pressed, then check the fuse or battery conections for tightnessor corrosion.
Fish signals, especiallyin shallow water,do not alwaysarch, but appear as irregularlyshaped marks. Fish arches are most likelyseen in 40 feet or deeper water, using a zoom range (for example40 to 60 feet).Read the section "Fish Signals" on page 25.
SENSITIVITY When firstturned on, the X-3 is in the AUTOSEARCH mode. This means the sensitivityand range are being automaticallyadjusted by the microcomputer to find and lock onto the bottom. Thesensitivity can be leftin the automatic mode,or it can be manually adjusted higher or lowerto suit conditions. The sensitivitylevel settings are displayed by a horizontal bar at the top of the display.See Figure 2. When the sensitivityis at minimum,the bar is very short As sensitivityis increased,the bar will travel to the right increasing in length correspondingwith the higher sensitivityselling. When the sensitivity is set to maximum, the bar will run completely across the top of the display from left to right TheAUTO key at the top middle position on the keyboardtUrnsauto sensitivityoff and on. Press it once, and autO sensitivityis turned off. Press it again, and auto sensitMty will be turned ott The auto annunciator is below the sensitivitybar, and canbe seen when the auto sensitivityis on.

CHART SPEED When theX-3 is firstturned on, the chartspeed runs at a pre-determined
they usually remain, helps you get the most from your X-3. Tofind the different temperatures,a surface temperaturemeter, such as the LDT-3000 is a valuableaid to your fishing.This unit provides an extremelyquick responseto identifyingthe desired surface water temperaturesfor various species. The temperatureof water in the lake is seldom constantfrom top to bottom. Layersof differenttemperaturesform,and the junction of a warm and cool layer of water is called a thermocline.The depth and thickness ofthe thermocline can vary with the season or time of day. In deep lakes there may be two or more at differentdepths.Thermoclines are important to fishermen becausetheyare areas where fish are active. Many times bait fish will be abovethe thermocline whilelarger game fish will suspend in or just above it
TheX-3 can detect this invisible temperaturelayer in the water, but the sensitivitywill probably have to be turned up to see it

At times it is desirable to stop or "freeze"the display to examinean echo.
Pressingthe STOP/RESUMEkey once wil freeze the display.While the display is stopped, theverytop of the surface line will flash on and off to signify that the unitis in the freeze mode. PressingSTOP/RESUMEagain will start the display moving at the last chart speed setting.
TheX-3 has many different functions,but only a limited amount of space for keys. Therefore,some of the keys have morethan one function.The key's primary function is printed very large, whilethe secondary function is printed underneathwith small letters of a different color. The key in the middle of the bottom row labeled2nd must be used to access the
secondary functions of the keys.
For example, the 9 key hasa small label beneaththe number nine that says "LIGHT". If you press the 9 key by itself, the X-3 thinks that you want the number 9. However,ifyou press the 2nd key first, then press the nine key, the X-3 will turn on the lights in the display.The2nd key just reassigned the meaning of the 9 key from a 9 to LIGHT PDF compression, OCR, web-optimization with CVISION's PdfCompressor
SURFACECLUTTER Themarkings at the top of the screen representthe surface of the water
which can extend manyfeet below the surface.This can interferewith fish signals or other targets. It's called Surface Clutter and is caused by algae, plankton, air bubblescaused by wave action or boat wakes, bait fish, or temperatureinversions.
CLEAR Ifyoupress a key that is not whatyouwanted, you canwait six seconds before pressing another key and the X-3 will automatically clear or "forget"the last key entered.
For example,if. you wish to turn on the lights,the proper keys to press are 2nd-9. However, if you accidentally pressed the 0 key instead of the 2nd key by accident,you could wait six seconds until the 0 disappears from the screen, then press 2nd-9.Another quick wayto clearan incorrect entry is to press 2nd-O and the last key enteredwill be erased.

These marks are normal and can be seen at any timeduring the year.It's usually the worst in the spring and summer,slacking off in the fall and
The entire display maybe erased by pressing 2nd-0-O. Everything except the digital numbers(if turned on) will be cleared fromthe display.
Although the X-3 will automaticallychange the range whenever the bottom getsshallower or goes deeper,thereare times when it is desirable to expand the range, or look at a differentsegment ofthewater below. Therange can be setanywherefrom 0 to 989 feeton the upper limit and 10 to 999 feet on the lower limit, provided the lower limit is no closerto the upper limit than 10 feet.
WATER TEMPERATURE AND THERMOCLINES Water temperaturehas an importantif not controllinginfluence upon the activitiesof all fish. Fish are cold blooded and their bodies are near the temperatureof the surroundingwater. During the winter, this slows down their metabolism so that they can only utilize about a fourth as much food as they consume in the summer.
Most fish don't spawn unlessthe water temperatureis within rather narrow limits. Trout can't survivein streams that get too warm; bass and other fish eventually die out when stocked in lakes that remain too cold during the summer. So fish will do without food rather than venture into waterthat is too hot or too cold; others will shift position for a temperature change as slight as one-half of one degree. While some fish havea wider temperaturetolerance than others, each of them has a certain range within which it tries to stay. Schooling fish suspended over deep waterlie at the level that providesthis temperaturein which, we assume, theyare the most comfortable.
When the X-3 is firstturned on, the AUTO RANGE function is enabled. It may be turned off anytimeby pressingthe 2nd key, then the 8 key. (In this manual, pressingkeys in sequence as just described will be shown like this: 2nd-B.) TheAUTO RANGING annunciator in the bottom right hand corner ofthe displaywill disappear,signifying the automatic ranging capability hasbeen tumed off. To return to the AUTO RANGE mode,simply press the 2nd-8 keys again and the unit will automaticallytrackthe bottom and place it in the lower 4/5 of the screen.
There are ten scale markers printed on both sides of the X-3's display to help determine whatthe depth of a target is. For example, if the depth range is 0 to 60 feet, then each mark is equal to six feet. If the target (such as a fish) was next to the 5th line, then it is 30 feet deep (5 lines times six feet=30feet). To make it easier to use the depth scale, use ranges in multiples often, i.e. 10, 30, 140, etc.
For example, to set the range from 0 to 31 feet, press 3-1 -LOWER LIMIT.
If a partial arch occurs mostof the time on your unit(the mark curves up, but not back down, or vice-versa)it could be the transducer is not pointed straight down. If the transducer is mounted on the transom, adjust it until the fish show the distinctive arch. Thismay take some trial and erroruntil the correct mountingangle is achieved.
NOTE: Although the maximumlower limit of the X-3 is 999 feet, the actual depth that the X-3 will reach is dependenton the water conditions, bottom conditions,and the quality of the transducer installation.
It is often desirable to expanda section ofthedisplay to show more detail. This is made possible on the X-3 by using the UPPERLIMIT key. To change the upper limit of the screen,simply press the desired depth (any numberbetween0 and 989 feet) and then the UPPERLIMIT key. The only restriction on the upper limit is that it must not be closerto the lower limit than 10 feet. In other words, if the lower limit is setto 81 feet, the upper limit cannot be set any closer than 71 feet A ten foot segment or larger (20, 30, 120, etc.) is required.
Upper and lower limits may be set in various combinationsto show segments from the surfaceto the bottom and nearly anywhere in betweento expand or "zoom" a portion of the display.If a ten foot segment is chosen, then the screen resolution is 1". This meansthat each dot is equal to 1 incheswhena ten foot segment is chosen.

Example: Set range to 16 to 31 feet Press: 1-6-UPPER LIMIT then 3-1 LOWER
The20 degree transducer is almost always the best to use in fresh water, while the 8 degree is used mostly in salt water In a deep water environment, (300 feetfreshwater, 100 feetsalt water) the narrow coneangle is more desirable because it can penetrateto much deeper depths since the sound energy is concentrated in a smallerarea.
Both the 8 degree and the 20 degree transducersgive accurate bottom readings,even though the bottom signal is much wideron the 20 degree model because you are seeing more ofthe bottom.Remember, the shallow edge ofthe signal shows you the truedepth.The rest of the signal tells youwhetheryou are over rocks, mud, dropoffs, etc.
Saltwater boats need to have the transducerpaintedwith a thin coatof anti-foulant paint to prevent organismsfrom growing.If unchecked,barnacles and othermarine growth will cause a decrease in the transducer's sensitivity. Do not use a metal based anti-foulantpaint as it will decrease the transducer's sensitivityalso. There are special anti-foulant paints carriedby most marine dealers specificallydesigned for
NOTE: When the X-3 is in the AUTO RANGE mode, the upper limit may be changed at anytime. If the upper limit is changed while the unitis in theAUTO RANGE mode,the X-3 will continueto select a lowerlimit that will keep the bottom displayed in the lower portion of the screen.
(PtGrTAL DIGITAL A complete digital sonar is incorporated intothe X-3. It automaticallydis-
criminates betweenthe valid bottom echoes and false echoes from fish, thermocline, or surface clutter Thedigital displaywill show only the bottom depth. It may be used at anytime, in conjunction with anyother mode theX-3 may be in (with the exception of FASTRACK or High Speed Scroll modes described in the AdvancedOperation section of this
Becauseyour X-3 is both extremelysensitiveand powerful, it cangive youan accurate picture of the kind ofbottom over whichyour boat is passing. A bottom offirm sand, gravel, shell, or hard clay returns a fairly wide signal. If the automatic sensitMty is turned off, and the signal narrows down, then it means thatyou have moved over a mud bottom. Mud absorbs the sound waves and returns a weak signal. Turn up the sensitivity. If you have the automatic sensitivityturned on, watch the sensitivity bar. As the boat passes over the mud bottom,the X-3 will automaticallyincrease the sensitivityto maintaina good bottom signal. The sensitivitybar will help you in determiningifthe bottom is softor hard. If it increaseswhile in the same depth of water,then the boat has moved over a soft bottom.If it decreases,then it is over a hard bottom.Of course,as the water depth increasesor decreases,the sensitivitywill change, also. Big rocks or stumpson a smooth bottom send back signals above the bottom, the distance depending upon their height If you watch as you approach a post or a tree stump, it will be clealry visableas a short line extendingabove the bottom signal.
When the X-3 is turned on, the bottom depth will be displayed on the screen.
TRANSDUCERS AND CONE ANGLE Thesound waves from the transducr go down ihtothe water in a cone shaped beam, much like the beam frOm a flashlight Theangle betWeen the outside edges ofthe cone is called the cone angle.
Lowrance offersa choice of transducers with either an 8 or 20 degree cone angle that will interchangewith any!of the 192 kHz sonar products. In otherwords, any Lowrance sonar instrumentcan be used with any Lowrance transducer of the same frequencywithoutretuning of any kind, and no loss of performance.However, the use of any other manufacturers' transducerwill result in a loss of performance.
Generally, wide coneangle transducers (20 degrees) are ideally suited
for operatingin shallow to mediumwaterdepths.The20 degree cone angle allows youto see more of the underwaterworld.In 15 feet of water the 20 degree cone covers an area that's about six feet across. The8 degree transducercovers only about a two foot circle.
For easier reading,the size ofthe digital numbers can be doubled by pressing2nd-2.To return them backto the smaller size, press 2nd-2 again.The numbersmust be displayed on the screen before you press 2nd-2.
Depth Diameter _________
Cone Angle 18ft.
To turnthe digital displayoff, or back on again, press 2nd-5.
Even if the digital numbersare not being displayedon the screen,the digital sonar will still continueto function.If the digital loses the bottom signal,the chart display will stop until the digital finds the bottom. If the digital numbersare being displayed on the screen,the chart display will stop, but the digital will flash the last valid bottom depth until it regains the bottom signal.
Wheneverthe X-3 is in the auto-sensitivity mode, it will adjust the sensitivity of the unitto threesteps above the minimum required to pick up the bottom signal. (Thereare 32 steps of sensitivityavailable.)
Thesensitivity maybe adjusted while the X-3 is in the auto-sensitivity mode. This may be desirable if the level of sensitivitythat the X-3 picked is not enough to showfish or other detail. Once the sensitivityhasbeen changed,the X-3 will increase the sensitivityenough to pick up the bottom signal,then add the level that you programmedin.
For example, if it tookthe X-3 five stepsof sensitivitytofind and lock onto the bottom, it will add threemore steps for a total ofeight If desired, any amount of sensitivityup to 24 (for a total of 32) may be added. Or, three steps of sensitivitycould be subtracted,howeveronly the bottom signal would be displayed at this low sensitMtysetting. There are two ways of adjustingthe sensitivitywhilethe X-3 is in the auto-sensitivitymode.
If the chart is in thefreeze mode,the digital displaywill continue to show the bottom depth as it changes. It does not freezewhen the chart does. Thisgives an accurate means of determiningthe precise bottom depth at all times. In fact, theX-3 can beturned into a digital sonar by pressing 2nd-0-5.Thiswill clear the screen of all echoes, including the bottom signal, and increase the size ofthe numbersfor easier viewing.
To display the bottom and other echoes again, press the STOP/RESUME key in the chartsection of the keyboard.
Thefirstis to press either the right arrow key>to increasethe sensitivity or press the leftarrow key <to decreaseit Ifthe value goes below the minimum required to keep the bottom signal,the X-3 will "chirp' The same is true if you try to go above 32 steps. As you press the arrow key, the sensitivitybar will move to the leftor right, according to the amount of
sensitivitychosen. The second method allowsyou to enterthe amount of stepsusing the number keys on the keyboard.For example, to adjust the sensitivityso that it will always beten steps abovethe minimum required to lock onto the bottom, press the 1 -0-AUTO keys.Thesensitivitywill then increase to ten steps above the minimum required, insteadofthree. Remember, the total number of steps is 32.
TheX-3 has two alarms,a chart alarm and a depth alarm. The chart alarm requires both an upper limit and a lower limit setting. Thealarm then "sounds off" whenever an echo (such as a fish) is detected inside the boundaries setby the upper and lower limits. Thedepth alarm also allows an upper and lower limit but it sounds whenever the bottom echo is detected outsidethe boundaries set by the alarm's upper and lowerlimits. Both chart and depth alarms can be set, then switched backand forth. However, they cannot be used simultaneously and will be treated separatelyin this section.
If an incorrect entry is made,wait six seconds for itto disappear,then enter the desired number. Or, press 2nd-O within six seconds of an entry and it will erase the last keystroke.
Press 2nd-FAST or SLOW to display the chart speed bar without chang-
ingthe chart speed.
When changing the upper or lower limits, rememberthe minimumdistance betweenthe two is ten feet. If a distance smaller than ten feet is pressed,the unitwill move the range to a ten foot separation.For example, if the upper limit was 0 and 9-LOWER LIMIT was entered, the X-3 would disregard the 9 and set the lower limitto ten feet
